Questions
Braintrust and Polygon Io, answered
What can start an automation from Braintrust?
Any of Braintrust's 2 triggers in the catalog, including New Event and New Project. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Polygon Io when something happens in Braintrust?
Any of Polygon Io's 12 actions, including Get aggregate bars, Get daily open/close, Get market status and Get previous close. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Polygon Io to Braintrust?
Polygon Io has no triggers in the catalog today, so automations start in Braintrust. If you need the other direction, ask: your agent reads Polygon Io's API documentation and adds it.
Do I have to build a connector for Braintrust or Polygon Io?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Braintrust and Polygon Io without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
